The API Vision Channel Strip is part of Universal Audio’s groundbreaking entry into microphone preamplifier and channel strip plug-in emulation with Unison™ integrated mic preamp technology. Based on API’s flagship Vision console, the UAD API Vision Channel Strip plug-in is the easiest way to turn your DAW into a colorful analog console, as it features the same indispensable API modules available in the famed console — the 212L Preamp, 215L Cut Filters, 550L EQ, 225L Compressor/Limiter, and the 235L Gate/Expander.
Apollo’s mic preamplifiers are digitally controlled and offer high-resolution, ultra-transparent translation from microphone to converter. While fantastic sounding on their own, these preamps are also designed as an ideal starting point to add processing color through Unison-enabled UAD plug-ins. Specifically, Unison plug-ins control the analog impedance and gain structure of the Apollo’s physical mic preamps — so hardware and software works in tandem to very convincingly emulate classic tube and solid state preamp designs.
Simply load the Unison plug-in into the “PREAMP” insert in the Apollo Console software. This enables near-zero latency recording with Mic, Line or Hi-Z inputs through the target preamp model. In addition to physical gain and input impedance control of the Apollo’s hardware preamps, Unison technology allows tactile control of preamp parameters. See the Apollo Software Manual Unison technology chapter for more information.
Yes. Unison-enabled UAD plug-ins can be used as standard UAD plug-ins inside your DAW of choice, or as realtime inserts in the Apollo Console. The Unison plug-ins are great for adding color and tone with any UAD-2 hardware, but the hardware preamp interaction is only possible on Apollo DUO, Apollo QUAD, and Apollo Twin (i.e., devices that have physical mic preamps).
Apollo’s preamp operation does not feature input impedance switching, so no user access to the function was required. While the circuit has always been present in the unit, the feature is now operational to match the modeled input impedance of current and future preamp emulations, whether fixed or switchable (like the 610-B) providing physical, microphone to preamp resistive interaction.
The API Vision Channel Strip's 212L module is internally padded to work at appropriate line level within the Apollo Console or your DAW environment. Use the API Vision Channel Strip as you would any other UAD plug-in, but with the benefit of modeled API input amplification as the first stage of the plug-in.
UA’s 550A plug-in models an original 1970’s, 3-band 550A with the original frequency selections and amplifier behaviors. The 550L, on the other hand, is nearly identical to the modern API 550B 4-Band EQ (available in the API 500 series format), with the same expanded features and frequency selections. The API 550L on the Vision Channel Strip plug-in is exclusive to the UAD platform and is not available anywhere else except as part of the actual API Vision console or other modern API Consoles.
